Best Programming Model for Low Power Design: Asynchronous Programming

Asynchronous programming can create efficient programs that are fast and resource-saving. It allows high concurrency in a single-threaded environment and can implement TCP/IP protocol stacks without an operating system. Fast and resource-efficient, it can keep power consumption at the lowest level, making asynchronous programming the best programming model for low power design. Three Realms There … Read more
